Structural Design Patterns in Modern C++ - Bridge Implementation

The video tutorial explains the bridge design pattern by creating a new project with two hierarchies: abstraction and implementation. The implementation hierarchy includes classes like GDI and OpenGL for rendering, while the abstraction hierarchy involves shapes like Line and Circle. The tutorial demonstrates how to decouple abstraction from implementation, allowing independent variation. It concludes with testing the implementation and discussing future extensions.
